JOHN '1. SHEROD. OF KANSAS CITY. KANSAS COMBINED DRILL-P111153 AND BORING-MACHINE.

To all whom it may ronrrrn:

lie it known that. l. .lonx 'l. citizen of the l'nited States. Kansas (ity, in the count) and State of hansus. haw inu-ntrd a new and useful Improvenu-nt in ('omhim-d Drill- Presses and lloring-llarhinw. of which the following is a spm-ilieation.

This invention relates to a combined drilling and boring nun-hintwhirh may he op-, crated either by hand or by foot power. or driven by any suitable motor.

Sin-1min. a l't itlill,' at of 'yandotte Specification of Letters Patent. Application filed March 19. 1909.

The object of the invention is u nun-hintof this kind which will occupy only a small amount of spare, and which is designed for use in connection with round houses. ltN'U- motive repair shops. and similar liltlt't'S when? an easily operated nu-tal \\orltin; machine is daily required.

'ith the above ohjert in view. my invention consists ill the novel features of eonstl'ut'tion hereinafter desrrilied. pointed out in the claims and shown in the :u't'n|i||i:t|| ing drawings, in whirh:

' Figure l is a side eleration. front elevation. Fig. 2! is a being removed. tion on the line -t---t being shown in plan. Fig. I is a detail rear view, the bearings for a tool stand being shown in section. Figs. ti, 7 and 8 are detail views of a feed shifting mechanism audits bearin 's.

In t liese drawings 1 repre ents the bed plate of a suitable stamhnmunted above which is a face plate or rhneh 2 )rovidetl upon its under side with gear teet I 3', and having a worm gear 4 formed upon its depending shaft 5. The lower portion of the shaft is reduced below the worm ear thereby forming a suitable shoulder w iieh turns a on ball bearings 6. The. reduced mrtion 0 the shaft is journaled in a split s eeve 7, the sleeve being provided with laterally extending lugs 8 through which works a screw 9, and by tightening said screw and drawing the lugs t'gether, the shaft 5 is clamped in the said sleeve 7 and the face )late 2 locked against rotation. A tool head stand 10 swings in a horizontal plane above the face plate .2 and carries a slitlahle tool holder 11 which is moved along the stand it) b means of a threaded feed rod 12 which is provided with a handle 12-! at one end and a drive wheel 14 at. the opposite end. The

Fig. 2. is a plan low, The Fig. -l is a set:- of Fig. l, certain gears head 11 carries a suitable cutting tool 15 adlatented :lnne 1910. Serial No. 484386.

jnsted by means of a handle it This tool head is of the ordinary t \pe. and any of the tool heads now in vonnnon use can he (implored. The stand lt is provided with a tltfllt'll llllg llt| IT which travels upon ball bearings I carried by an upright post or standard it) which rises from a rornerpf the bed plate the said post receiving a \ettiral shaft in formed integral with the bos 1?. the details of this mounting being shown in Fig. 5.

The teeth 3} of the face date 2 mesh with a gear wheel 2! carried iy a shaft 2;. which in turn carries a gear wheel .23 which meshes with a larger gear wheel 24. pitan 2.3 connects the gear wheel -24 with the drive wheel ll of theft-ed rod 12, thereby rennet-ting the face plate and the tool head ll Mi that the tool may he run in unison. 'l'he pitinun .25 is detarhulilv connected to the gear wheel and by disconnecting it from either or both of these wheels the fare plate or the tool helad may be operated i|ule wndently of eueh tit lt'l'.

t) a shaft 2" extending from the front of the derive and jonrnaled in adjustable bearings 27 is fixed a gear wheel 28. This shaft has also fixed upon it a hand wheel 29 and stepped pulleys 30 over which runs a belt. 31. The belt is driven from a drive pulley 32 fixed upon a shaft 33 which shaft may be driven from any suitable source of power. This )Gl'lllllS the driving of the shaft 26 either y hand or by power. 'lhegearwheol 2b is adapted to mesh with either a gear wheel 34 or 35. The gear wheel 84 is carried by a shaft. 36 which carries a worm 37 which meshes with the worm gear 4 of the face plate 2, and when the gear 28 is thrown into on mgemcnt with the gear wheel 84 and the she t 26 is rotated the face plate 2 will rotated, and will in turn drive the gear 21 and operate the tool head by means previously described. The gear wheel 85 is fixed upon a shaft 38 which carries a beveled gear 39 which meshes with .a beveled gear 40 carried by the lower end of a shaft 41 which extends upwardly through a ro tatahle standard 42 of the drilling pm The shaft 41 is provided at; its upper end with a beveled gear 43 and throng a auitable series of gears operates drilling mechanism 44. The' drill rose is also of the usual construction an it. is not therefore thought mmsaary to describe in detail its 2'4 and the (rive wheel H,

various arts. Like the tool head stand the standa 42 sup rting the drilling mechanism is nioiinted upon ball bearings 45 so that the drill press can be swun zontal plane and brou ht immediately above or swung away from t- 0 face plate 2.

In order to throw the gear wheel 28 into engagement with either of the gear wheels 34 or 35, thus operating either the face plate or the face plate and tool head, or leaving both of these inoperative and driving the drilling mechanism only, the bearings 27 of the shaft 26 are adjustable and are constructed and operated in the following manner: bracket 46 is secured upon the under side of the bed plllLU adjacent the front edge and this bracket is cut away midway its eiids as shown at47 and is also vertically slotted as shown at 48. The bearings 27 are provided with a dc nding portion 49 which extends downwartly through the slot 48. the bearings working in the cut-out portion 47 of the bracket 46. A shaft 50 passes transversely through the bracket 46 and through the slot 48, the extension 49 of the bearings 27 being fixed upon said shaft. This shaft rocks in the bracket 46 and is operated by means of a handle 5i lfliltli tfill'l'litfti a hand filmliziltl 'ri ing am 52, w iici en a 'es a me 53 iiiliii zd'loy a side. of the lii'ai lv't t. 'lliis rack is provided with two notches and by briii ing the pawl 52 into engagement with t is upper notch, the shaft no is rocked thus swin in v the bearings 27 and the shaft 26 and 0c ing the gear wheel 28 into engagement with the gear wheel 85. By moving the handle downwardly and brin 'n' the pawl 52 into engagement with tie ower notch of the rack 53, the shaft 50 is rocked in the other direction and the gear 28 is brought into engagement with the gear wheel 34. The details of this maisti'uetion are in a horishown in Figs. 6 7 and 8, the last mentioned figure being a p an view of the bracket 46 with the shaft 50 and the bearings removed.

It will be obvious from the above description that-ii combined drilling and borin' machine provided also with a cutting too holdercan be used in many ways, and is ada ited for use in connection with metal \VOl'ltlli" of various kinds, and will be found especially adapted for use in connection with en ine boasts, railroad repair shops, etc.
